<div class="g1t-endpoint"><span class="g1t-method" data-method="post">POST</span><code>/repos/{owner}/{name}/detach</code></div>

Needs the Admin role on the fork. Its code, settings, and the pull requests it already opened into the parent stay as they are; it can no longer be synced or open new pull requests into the parent. It cannot be attached again.

The repository, now with no parent. Needs the Admin role (`403` otherwise); `422` when it is not a fork. It cannot be attached again. See [Detach a fork](/guides/forking-repositories/#detach-a-fork).
